The computer-implemented method includes obtaining, at an authentication server, a current location and an associated time from a client device of the user over a communications network; determining, by a hardware processor, a location score based on a correlation between the current location and the associated time and a historical location and a historical time that are associated with the client device of the user; determining, by the hardware processor, a risk assessment score based on the location score; and providing, over the communications network, an authentication verification for the user to perform one or more actions with an online resource based on the risk assessment score.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 16/249,773, (now allowed), which was filed on Jan. 16, 2019, the entirety of which is incorporated by reference.

FIELD

The present disclosure relates to authenticating a user, and more particularly, to authenticating a user with an online resource based on location information.

BACKGROUND

Traditionally, authentication for certain online resources, such as financial or government services or accounts, is performed using single factor or multi-factor authentication. Single factor authentication uses a single credential for authentication. Typically, the single credential is a password. Improvements have been made to the strength of the password that is used by including additional types and numbers of characters; however, these improvements do not change the fact that the password is still a single piece of authenticating information. Multi-factor authentication extends the single factor authentication by adding one or more additional authenticating credentials to the single credential. These one or more additional authenticating credentials can include information related to the user themselves, such as biometric information, and special security information that the user possesses, such as a token or a one-time password. Even with conventional multi-factor authentication, however, online resources are still vulnerable to exploitation by a determined attacker or entity.

Therefore, a need exists for improved authentication systems and methods. To that end, the subject disclosure addresses and reduces the vulnerabilities of existing authentication techniques by using additional credentials that include information related to a user's past movement behavior.

BRIEF SUMMARY OF THE INVENTION

Generally speaking, the present disclosure describes devices, computer-implemented methods, systems, and non-transitory computer readable medium that authenticate a user by monitoring a user's travels over time and using that information in combination with the user's location when being authenticated to determine a risk score and/or an access level for the user that may be used, for example, to access an online resource that the user wishes to utilize.

The present disclosure is generally related to authenticating information, and, more specifically, to methods, apparatuses, and computer program products for authenticating a user. Implementations of the methods, apparatuses, and computer program products disclosed herein provide for obtaining, at an authentication server, a current location and an associated time from a client device of the user over a communications network. The present disclosure further describes determining, e.g., using a hardware processor of the authentication server, that the current location and its associated time is at or near or otherwise corresponds to a historical location(s) and a historical time(s) associated with the user. Various implementations described herein can calculate or determine, e.g., using the hardware processor, a location score based on the degree of correlation between the current location and the associated time and the historical location(s) and the historical time(s). Various implementations described herein can also calculate or determine, e.g., using the hardware processor, a risk assessment score based on the location score and in some implementations, on other factors. Various implementations may also provide, e.g., over the communications network, an authentication verification for the user, which may enable the user to perform one or more actions with an online resource, where the enabled actions may be based on the risk assessment score.

As such, implementations consistent with the present disclosure provide a particular, technically advantageous computer architecture that improves security for user transactions, including, for example, financial transactions such as establishing bank accounts, fund withdrawals, and fund transfers. In certain implementations, an authentication server or system may be used for monitoring the current location of user, e.g., an existing customer of a financial entity (e.g., a bank customer), determining whether the current location of the user is consistent with past locations of the user, and calculating or determining a risk score for the user, which may be a function of the consistency between the user's current location and one or more of the user's past locations, optionally at approximately the same time of day, in order to permit the user to perform an action and/or access a resource, for example, permit a customer to perform a transaction with the financial entity. As such, implementations consistent with the present disclosure provide a particular, technically advantageous system to reduce the instance of fraud associated with user actions (e.g., financial transactions) and improve security when verifying a user because a fraudulent actor impersonating the user is very unlikely to know, or to coincidentally be at, a location that the legitimate user frequents, especially at the same time of day. Moreover, a legitimate user's movement patterns and location history are very difficult for a fraudulent actor to discover, other than by physically following the user for several days, which makes location information a very secure authentication credential compared to conventional credentials such as passwords.

Various implementations consistent with the present disclosure leverage the wide-spread use of mobile personal communication devices (e.g., smart phones) that have location finding or tracking abilities (e.g., GPS and/or multilateration between cell towers) to facilitate identity verification of users. For example, a financial entity, a government agency, or a third party may provide a downloadable software application to the user to install on their mobile communication device, where the software application is designed to collect location information of the user to provide a proof-of-identity in the form of location records that are used, for example, to generate a risk score.

FIG. 1 is a block diagram illustrating an example of an operating environment for authenticating a user according to one or more implementations of the disclosure. As shown, the operating environment 100 may include one or more systems including a client device 104, an authentication server 114, a database 122 that stores previously collected user location information, and a network 112 that communicatively connects the client device 104, authentication server 114, and database 122, such that they can interact with each other. In various implementations, the environment 122 may include various other systems (not shown) such as banking/financial systems, which may interact via the network 112. The network 112 may be any type of wired or wireless network including a local area network (LAN), a wide area network (WAN), or a direct communication link, or other suitable connection.

The client device 104 may include an application 108 (or application software) which may include program code (or a set of instructions) that performs various operations (or methods, functions, processes, etc.) as further described herein. For example, the application 108 may be or include any type of “app” such as a financial application, account enrollment application, government service application, etc. In some implementations, the application 108 enables a user 102 to access or sign up and apply for financial products and services such as bank accounts, loans, credit cards, mortgages, retirement savings accounts, brokerage accounts, mobile and online payment services (e.g., the Venmo™ and PayPal™ services from PayPal Holdings, Inc. of San Jose, Calif.), and other financial services and the like. In other implementations, the application 108 enables users to access or enroll in government services such as school enrollment, voter registration, online voting, absentee voting, registering for computer based trainings or tests (such as certification exams), a national health insurance program (e.g., Medicare), social security benefits, unemployment compensation, federal student loans, the National Flood Insurance Program (NFIP), Supplemental Nutrition Assistance Program (SNAP) benefits, and the like.

In certain implementations, the application 108 may be an application usable to manage an existing account 110 of an account holder or customer (e.g., the user 102). For example, the application 108 may be usable to perform online transactions for a bank account, a brokerage account, a health savings account (HSA), a pension account, or a retirement savings account (e.g., a 401(k) or individual retirement account (IRA)). According to such implementations, the application 108 may require the account holder (e.g., the user 102) to provide or allow access to current location information, which the application uses to verify proof-of-identity based on a user's risk score, which may be calculated by comparing current locations visited with past locations visited. In some implementations, the application 108 may request the current location information in response to the account holder 102 initiating or requesting any transaction that is classified as requiring proof of identity or identity authentication, such as a high-risk or unusual transaction. Such further proof-of-identity information may be required even though the user 102 is already logged into the account 110 using an account ID and password or other conventional multifactor identification.

The application 108 communicates with a location determining unit 106, e.g., a global positioning receiver, of the client device 104 to obtain location information (e.g., GPS coordinates such as latitude and longitude, or the like) and provides the location information to the authentication server 114. The authentication server 114 communicates with the database 122 to store and retrieve location information associated with the user 102. For example, in various implementations, the database 122 comprises a location history 124 of a user 102, and the history 124 contains a set of several records. For example, the location history 124 may include a set of records or rows that each store an identifier of the client device 104, a sample or snapshot of the client device 104's location (e.g., GPS coordinates specifying the user 102's location), and a time, (which may include a date, day of the week, and an hour and minute), at which the location snapshot was recorded. The authentication server 114 can obtain location information, which may including data such as the client device identifier, the location datum, and the associated time datum, from the client device 104, and the authentication server 114 may provide this information to the database 122 to be stored in the location history 124 as a new record.

The authentication server 114 can comprise a location receiving unit 116, a location correlation unit 118, and a risk score calculation unit 120. In operation, the location receiving unit 116 of the authentication server 114 receives location information from the client device 104 over time (e.g., periodically, such as every 2 minutes, or every 3 minutes, or every 5 minutes, or every 7 minutes; or whenever triggered by a specified event, such as when the user 102 uses the application 108; etc.) and stores this information in the database 122, for example, in a manner that is indexed or searchable using the ID of the client device 104, which corresponds to the user 102 of the client device 104.

In various implementations, when the authentication server 114 authenticates the user 102, such as when requested by the application 108, the authentication server 114 issues a command to the client device 104 to send the current location of the user 102 to the location receiving unit 116. The location receiving unit 116 also issues a command to the database 122 to obtain information about the past location history 125 for the user 102 (i.e., for the device 104). The location correlation unit 118 receives the location information (e.g., the current location and at least part of the location history 124) from the location receiving unit 116 (or directly from the database 122) and calculates or determines how close the current location is to (i.e., the distance from) the historical location(s) from the location history 124 at the same or about the same time of day and/or day of the week. As noted, the location information includes time information (e.g., a timestamp), and in some implementations, the location correlation unit 118 may also calculate or determine how close or near in time the timestamp of the current location is to the timestamp(s) of the same or nearby historical location(s). Various embodiments of the location correlation unit 118 employ an algorithm that calculates a degree of correlation between the current location and the historical location(s) based on the distance between locations, such that the degree of correlation is a function of the difference in distance between the current location of the user 102 and the historic location(s) of the user 102. For example, if the distance difference is small, then the degree of correlation is high. In some embodiments, the degree of correlation may also be a function of the difference in time between the timestamp of the current location and the timestamp(s) of the same or nearby historical location(s). For example, if the time difference is small, then the degree of correlation may be raised higher. The location correlation unit 118 may then create a location correlation score based on the degree of correlation and supply it to the risk score calculation unit 120.

The risk score calculation unit 120 receives the location correlation score and uses it to determine a risk assessment score for the user 102. The risk assessment score is a measure of how confident the model determines that the person is who he/she claims to be. For example, the location correlation score will be high if the location detected for the user 102 is his frequently visited places, which may be an indicators for low overall confidence level to say that the person seems to be who he/she claims to be. Hence, a grant of authentication can be make. Additionally, other decision factors may be used in deciding the grant of authentication. On the other hand, if the location detected when the person is asking for an authentication is far away (for example, current location is Italy when the location detected previously is Washington D.C.) from a previously determined location, the location correlation score will be low. Hence, the risk level/score can be high and that person should likely not be authenticated. Various embodiments of the risk score calculation unit 120 employ an algorithm that calculates a risk assessment score based on the location correlations score and other factors or information, such as device authenticity score and how frequent location signals are collected. Thus, the lower the risk score, the more likely it is that the user 102 is the actual person they purported to be, (e.g., the genuine customer for the account 110); while a higher risk score indicates a higher degree of uncertainty that the user 102 is the actual person they purported to be (e.g., the genuine customer), which uncertainty is caused in some part by the client device 104 connecting from an uncustomary or atypical location and/or time of day.

In various implementations, the authentication server 114 may transmit or provide authentication verification information to the application 108 on the client device 104. The contents of the authentication verification information depends on the risk score, and in some implementations may include the risk score. For example, if the risk calculation unit 120 produces a low risk score, then the authentication server 114 may provide authentication verification information indicating that the user 102 may have full unlimited use of and access to the account 110 via the application 108; or if the risk calculation unit 120 produces a high risk score, then the authentication server 114 may request additional authentication information from the user 102 via the application and/or may restrict the type of access to the account 110 that is granted to the user 102. An example of restricted access is allowing the user 102 to see the balance in a bank account, but not allowing the user 102 to withdraw or transfer funds from the account.

FIG. 2 illustrates examples 200 of travel paths and locations according to one or more implementations of the disclosure. In this example, on a typical work day, the user 102 may leave home 202 at a first time (e.g., 7:00) and travel to a school 204 along the path 208, arriving at the school 204 at time 2 (e.g., 7:30) to drop the children off. The user 102 may then proceed to their work building 206 along the path 210 arriving at time 3 (e.g., 8:00). The user 102 may then leave the work building 206 (e.g., at 18:00) and travel along the path 210 to arrive at the school 204 at time 4 (e.g., 18:30), pick up the kids and then travel the path 208 to arrive home at time 5 (e.g. 19:00). On another day when school is not in session, the user 102 may travel directly from home 202 at time 6 (e.g. 7:20) to work 206 along the path 212 and arrive at work 206 at time 7 (e.g., 8:00). At various points along paths 208, 210, and 212, and at static locations such as the home 202, the work building 206 and the school 204, the client device 104 may transmit or otherwise communicate location information, including a timestamp, to the authentication server 114, which builds a location history 124 for the client device 104. The location history 124 is a profile of such location or movement behavior of the user 102 that is stored in the database 122, and that is used by the authentication server 114 to authenticate the user 102. The more detailed (e.g., the more frequent and/or the more voluminous) the location information that is collected from the user 102, the better (e.g., the more accurate) the profile the authentication server 114 can build, and the more accurate the authentication assessment will be.

In various embodiments, the user 102, on the client device 104, may provide an authorization to the authentication server 114 to collect location information of the user 102. For example, the user 102 may open the application 108 on the client device 104 and log in to the account 110 associated with the user 102. The user 102 can then select an opt-in permission in the application 108 to give permission to or permit the authentication server 114 to obtain location information from the user 102 to be stored in the database 122. The application 108 can access location information produced or obtained by the location determining unit 106 of the client device 104 using one or more features in a software development kit (SDK) and obtain the location information via an application programming interface (API). The authentication server 114 obtains, over a communication network, e.g., network 112, the location information from the client device 104 and stores the location information in records of the location history 124 of the user 102, in the database 122. The records can include information related to the user 102, the client device 104, the account 110, and the location. Each record stores associated time information (e.g., time stamp) for each location entry. In various implementations, this collection of location information and building of the location history 124 is done prior to the authentication server 114 attempting to authenticate or verify the identity a user 102 based on the user's current location at the time of the authentication request.

The authentication server 114 can create a model 121 of the activity of the user 102 based on the location information and associated times that are obtained from the client device 104. As the authentication server 114 obtains more location information over time, the model 121 can be more refined and can be a better reflector and predictor of the movement or location activities of the user 102 when in possession of the client device 104. For example, the model 121 can represent the typical daily activities of a user 102 based on past location/time information that has been obtained and analyzed by the authentication server 114. Continuing the example with respect to FIG. 2, a model of the typical (e.g. 90% conforming) location activity during the work week for the user 102 may be represented as shown in Table 1.

TABLE 1 Time Period: 1900- 0701- 0731- 0801- 1801- 1831- 0700 0730 0800 1800 1830 1900 Historical Home Path 208 Path 210 Work Path 210 Path Location: 202 or or 206 or 208 School Work School 204 206 204

The movement activity of the user 102 can occasionally vary in uncustomary or atypical ways for various reasons that do not fit into or conform to the model. For example, the user 102 may sometimes experience unusual traffic on the way 210 to work 206 that delays arrive to 8:30 am, the user 102 may go out for lunch or go shopping around midday every now and then, or the user 102 may sometimes leave work 206 earlier or later than normal. As the model is provided with additional location information over time, the model can become a better reflector and predictor of the location of the user 102 because the infrequent, uncustomary movements and locations are overshadowed and identifiable as atypical by being different from the large number of typical and routine movements and locations. For example, the model represented in Table 1 may be built based on the criteria that the user 102 (i.e., the client device 104) is at the listed Location (e.g., within a predefined radius of a specific geographical point or coordinate of that Location, such as within 200 meters or within 0.5 mile or the like) at least 95 times out of 100 during the listed Time Period. In other words the model may be built to be, for example, 95% accurate according to the data in the location history 124 of the user 102. In various implementations, other accuracies, such as 98%, 90%, 85%, 80%, 75%, or the like, may be used to model the typical movement activity profile. In various implementations, the model may be used as a factor in calculating a location score and/or a risk assessment score as part of a location-based authentication process. The location score is a measure of how confident the model determines that the location detected is where the actual identify of who owns the location history of the device is currently located.

FIG. 3 is a process flow diagram illustrating an example of a process 300 for authenticating via location monitoring, according to examples of present disclosure. The computer-implemented process 300 begins by obtaining at 302, for example by the authentication server 114, a current location and an associated time from a client device of the user over a communications network. In various implementations, the authentication server 114 may obtain the current location and time information when the client device 104 transmits it, unsolicited, to the authentication server 114, or the authentication server 114 may request the current location and time information from the client device 104, for example, in response to a notification from the application 108 that the user 102 is attempting to access or perform a predefined action with the account 110.

After obtaining the current location and its time (302), the computer-implemented method 300 continues by determining at 304, e.g., using a hardware processor of the authentication server 114, whether the current location and the associated time is at or near a historical location and a historical time associated with the user. Continuing with the example above, the current location information and associated time, (e.g., a global positioning system (GPS) coordinate) may be the location of work 206 at 9 am on Wednesday, and the authentication server 114 may compare this current information with historical location information for the user 102 that is stored in the database 122 to determine whether there is a correspondence or correlation between the current and past locations, which may be in association with the current time; e.g., how far the current location is from the user's typical historical location at that time of day.

The computer-implemented method 300 continues at 306 by calculating or determining, by the hardware processor, a location score based on a degree of correlation between the current location and its associated time and the historical location(s) and the historical time(s). For example, the server 114 can build a model 121 to determine an authentication result using raw data from the location receiving unit 116. The correlation score 118 being generated between the current location 116 and the location history 124, the risk score 120 is generated by determining how authentic the phone is and/or how frequent the location signals is generated.

For instance, FIG. 4 shows an example of a method 400 for determining the location score. The method 400, begins by retrieving, by the authentication server 114, at 402, the location history 124 of the user 102 from the database 122. The method 400 continues by filtering out, by the authentication server 114, at 404, entries or records in the location history 124 that are associated with or meet predetermined filtering criteria. For example, if the predetermined filtering criteria includes holidays and weekends, then the authentication server 114 filters out records of locations that the user 102 occupied on holidays and weekends; i.e., the authentication server 114 processes or uses only records of locations that the user 102 occupied on non-holiday weekdays. The method 400 continues by comparing, by the authentication server 114, at 406, the plurality of filtered locations from the location history 124 with the current location (from 302); where the locations from the location history 124 were taken or recorded by the client device 104 at approximately the same time of day as the associated time for the current location, (e.g., within plus or minus 5 or 10 or 15 or 30 minutes of the associated time for the current location). In some implementations, there may be no filtering criteria or variable filtering criteria.

In various embodiments, the comparing at 406 (or the filtering at 404) can further include using a predetermined or specified time frame to select (or filter) the records in the location history 124 so as to perform the comparing only on records that have timestamps within the time frame. For example, the predetermined time frame can be a prior day, a prior week, a prior month, or a specified number of prior days, such as 90 days.

The method 400 continues by determining, by the authentication server 114, at 408, whether the current location is within a predetermined distance from the historical location(s), (e.g., from the locations in the filtered records from the location history 124 that are being used in the comparing at 406 or from the location from a model, such as the model of Table 1, in implementations that employ a model), at approximately the same time of day, (or during the same time period of the day for implementations using a model such as the model of Table 1). For example, the predetermined distance may be 50 yards, 100 yards, 0.1 mile, 0.2 mile, 0.5 mile, 1 mile, 2 miles, 5 miles, etc. from the historical location and approximately the same time of day may be within +/−5 minutes, within +/−10 minutes, within +/−20 minutes, within +/−30 minutes, etc.

The method 400 continues by assigning (e.g., from a lookup table) or calculating, by the authentication server, at 410, the location score based upon the predetermined distance or a set of predetermined distances. For example, in some implementations, the location score may have a range from 1 to 100, with a higher location score indicating that the user 102 is closer to the historic location at the approximately same time of day. Thus, the location score represents the degree of correlation between the current location and time and the historical location(s) at a similar time, and a higher location score indicates a higher degree of correlation; e.g., that the user 102 is in or near an expected location for a given time of day as compared to past patterns of movement behavior. In such implementations the score may be proportional to or otherwise a function of the predetermined distance; e.g., if the predetermined distance is 17 yards and the current location is within that predetermined distance, then the score may 100 out of 100; if the predetermined distance is 0.1 mile and the current location is within that predetermined distance, then the score may 90 out of 100; if the predetermined distance is 0.2 mile and the current location is within that predetermined distance, then the score may 80 out of 100; if the predetermined distance is 0.5 mile and the current location is within that predetermined distance, then the score may 50 out of 100, and the like. In various implementations, the function need not be linear.

Returning again to FIG. 3, the computer-implemented method 300 continues by calculating or determining at 308, by the hardware processor of the authentication server 114, a risk assessment score based on the location score. A higher location score would result in a lower risk assessment score.

The computer-implemented method 300 continues by providing at 310, over the communications network, an authentication verification for the user 102, which may include the risk assessment score. In some implementations, the authentication verification may specify whether or not the user 102 is permitted to perform one or more actions with a resource (e.g., an online resource), where the actions that are permitted are chosen based on the risk assessment score. For example, the actions can include: viewing a financial account, performing a transaction in the financial account, and communicating with an authorized person managing the financial account, etc. The availability of an action among the group of actions is dependent on the risk assessment score. A lower risk assessment score permits more actions with the online resource. For example, if the person has a low risk assessment score, which indicates that it is a less risky identity, more higher risk functionality can be enabled to the person, such as allowing the person an online transaction including, but are not limited to, a fund transfer and a bill payment. If the person has a high risk assessment score, the person may be granted the ability to perform another set of transactions, such as, but are not limited to, access to view balances and set up direct deposits. If the person would like more access, the person may be need to provide further identification verification by, for example, calling in to an account specialist or perform additional steps, such as entering a one-time password or using a government issued verification information.
